Owing to the outstanding mechanical performance, diglycidyl ether of bisphenol A (DGEBA) becomes an important thermoset resin, but its brittleness and difficulties in degradation and recycling retard sustainable development. Herein, we have prepared several hyperbranched epoxy resins containing 1,3,5-hexahydro-s-triazine (HER-HT_n, n = 3, 6, 12, 24) which showed versatility on modifying DGEBA, including simultaneous reinforcing and toughening function, rapid degradation and recycling, and good compatibility. The detailed results showed that the HER-HT₁₂ could increase the flexural, impact and tensile strengths of cured DGEBA by 132.7%, 190.4%, and 57.7%, respectively, and also increase degradation degree from 37.2 wt% to 99.9 wt%. The mechanical performance of the cured HER-HT_n/DGEBA reinforced in the beginning and then decreased with an increase in the content and the molecular weight of HER-HT_n, however, their degradation degrees increased distinctly. The reinforcing and toughening mechanism and degradation mechanism of the composites were investigated by SEM micrographs and GC-MS spectra.

由于出色的机械性能，双酚A的二缩水甘油醚（DGEBA）成为重要的热固性树脂，但其脆性以及降解和循环利用的困难阻碍了可持续发展。本文中，我们制备了几种含有1,3,5-六氢-s-三嗪（HER-HT _n，n = 3、6、12、24）的超支化环氧树脂，它们具有改性DGEBA的多功能性，包括同时增强和增韧功能，快速降解和回收利用以及良好的兼容性。详细的结果表明，HER-HT ₁₂可以使固化的DGEBA的弯曲强度，冲击强度和拉伸强度分别提高132.7％，190.4％和57.7％，并且降解程度从37.2 wt％提高到99.9 wt％。固化的HER-HT的机械性能_n / DGEBA开始增强，然后随着HER-HT _n含量和分子量的增加而降低，但是它们的降​​解程度明显增加。通过SEM显微照片和GC-MS光谱研究了复合材料的增强，增韧机理和降解机理。
